How to Make the 15-Hour Potato: Step-by-Step Recipe
While the time commitment sounds daunting, much is hands-off. The technique creates a dense, sliceable loaf with distinct layers, which are then deep-fried to create rich, crunchy potato bars.
Ingredients
- Potatoes (Yukon Gold or Russet; about 5–8 medium)
- Fat (Duck fat, beef drippings, or clarified butter)
- Flaky sea salt (Kosher salt also works)
- Oil for deep-frying (peanut or another neutral oil)
- Optional: flavorings such as garlic confit, chiles, or herbs
Essential Equipment
- Mandoline (for ultra-thin, even slices)
- Loaf pan (approx. 8¼ x 4¼ inches works well)
- Parchment paper
- Heavy objects to weigh/press (cans or another pan)
- Thermometer for oil
Instructions
- Prep and Slice: Peel and thinly slice potatoes using a mandoline. Target slices no thicker than 1mm (paper thin).
- Toss in Fat and Salt: In a large bowl, toss potato slices in melted fat (duck fat, beef drippings, or butter) with a generous sprinkle of flaky or kosher salt. Ensure every piece is thoroughly coated.
- Layer in Loaf Pan: Line the loaf pan with parchment on the bottom and sides, then begin overlapping potato slices, pressing down gently every few layers. Pour a bit of fat between layers as you go.
- Bake Low and Slow: Cover with a parchment lid. Place pan in a preheated oven at 250℉ (120℃). Bake for three hours until potatoes are completely tender.
- Press and Chill: Once out of the oven, cover with more parchment, then weigh down with heavy objects (canned goods work) or a second pan. Chill the whole loaf, pressed, in the refrigerator for 10–12 hours to firm up and meld.
- Slice: Remove the cold, compressed potato loaf. Unmold and cut into 1-inch wide rectangles or cubes, which reveal the signature paper-thin layers inside.
- Deep-Fry: Heat frying oil to 375℉ (190℃). Fry the potato blocks, a few at a time, turning occasionally until deep golden and crunchy (about 3–5 minutes). Drain on paper towels.
- Season and Serve: Sprinkle again with flaky salt while hot. Serve immediately for maximum crunch and flavor.
Quick Reference Table: Ingredients & Steps
| Step | Details | Time |
|---|---|---|
| Prep & Slice | Peel and cut potatoes thin on mandoline | ~15 min |
| Toss in Fat | Coat thoroughly in melted duck fat, butter, or beef drippings | 5 min |
| Layer & Assemble | Press into lined loaf pan | 10 min |
| Bake | 250℉ oven, covered with parchment | 3 hours |
| Press & Chill | Press in fridge, weighted | 10–12 hours |
| Slice & Fry | Cut, deep-fry in 375℉ oil | 10 min active, 3–5 min each batch |
Flavor Variations and Adaptations
While traditionalists might stick to the standard fat-and-salt route, TikTok and Instagram have unleashed a wave of creative takes, including:
- Garlic Confit – Add mashed roasted garlic between layers for a mellow, fragrant kick.
- Herb-Infused – Sprinkle in dried thyme, rosemary, or sage.
- Chili-Spiced – Slice in red or green chiles for color and subtle heat, as seen from TikTok user @teawithmrt.
- Cheese Upgrade – Shave parmesan or comté between layers for savory depth.
Fat matters for flavor; duck fat offers immense richness, while beef drippings evoke classic roast dinner vibes, and clarified butter provides nutty sweetness.
Expert Verdict: Are 15-Hour Potatoes Worth It?
Despite the long timeline, most of the process is hands-off. Food writer Jun Loh, among others to rigorously test the method, summed it up: “Even though the whole thing took many hours to make, I’d give it a 10 out of 10 and would make again.” The textural contrast and deeply savory interiors astonish even hardened cooks.
However, patience is key: the baking and pressing time cannot be rushed. If instant gratification is your style, this method requires advance planning – but the dramatic payoff makes it a journey potato lovers will cherish.
Pro Tips for Perfect 15-Hour Potatoes
- Go thin or go home: A sharp mandoline is essential for uniform, translucent slices. Thick pieces won’t yield the signature layers.
- Don’t skimp on fat: Each slice needs a coating. This prevents sticking and produces those crackling edges.
- Absolute chill: Refrigerate the pressed loaf for the full recommended time – this makes slicing possible and improves the final crispiness.
- Oil temp matters: Use a thermometer, and fry at 375℉ for shatteringly crisp exteriors without excess greasiness.
- Tweak and customize: Experiment with seasonings and fats to make it your own.

Frequently Asked Questions (FAQs)
Q: Can I use other types of potatoes?
A: Most recipes recommend Yukon Gold for creaminess or Russets for fluffiness. The main requirement is that the potato holds its shape and slices thinly. Avoid waxier types like Red Bliss.
Q: Is duck fat required, or are substitutes fine?
A: Duck fat is classic for deep, savory flavor, but beef drippings or clarified butter also work. Olive oil is not recommended as it can overpower or burn at high temperatures.
Q: What if I don’t have a mandoline?
A: Precision is key—thin, even slices (<1mm) are ideal. A very sharp knife can work in a pinch, but a mandoline ensures the signature layered effect.
Q: Why press and chill for so long?
A: Pressing compresses the layers and chilling firms them up, which is crucial for the neat slices and the way they fry up crispy and intact.
Q: Can the baked, pressed loaf be prepared ahead of frying?
A: Yes! The loaf can remain, tightly wrapped, in the refrigerator for up to 24 hours before slicing and frying. This makes entertaining easier.
Final Thoughts: Is It Worth 15 Hours?
Absolutely—if you’re a fan of crispy, decadent potatoes and you relish a kitchen project. While it’s not a weeknight side dish, it’s a showstopper worth the wait. Customize with your favorite fats and flavors, savor the process, and enjoy TikTok’s gift to potato love in every glorious, shattering bite.
